Digital Product Agency
Custom Web Application Development
Useful for custom portals, dashboards, SaaS apps, customer tools, and operational platforms.
Strong fit when the app needs backend logic, integrations, authentication, and clean deployment.
Designed for US and UK clients that need a reliable remote technical partner.
Service overview
What it is
A custom web app becomes expensive when the frontend, backend, data model, integrations, and deployment path are built separately. Zyvor helps US and UK clients build web applications with the product workflows, backend logic, API contracts, and delivery rhythm needed for production use, with architecture support where it improves maintainability.

Common custom web app needs
How Zyvor approaches it
Focused builds usually start at four weeks. Complex builds with payments, integrations, or real-time systems can run longer. Scoping happens before development starts so timelines stay realistic.

View detailYes. I frequently extend, refactor, or add features to existing platforms. I assess the current codebase first to understand architecture, technical debt, and integration points.
Yes. Stripe integration, subscription billing, usage-based pricing, invoicing, and payment webhook architecture are all in scope.
It starts with the product goal, user workflow, codebase, stack, and delivery context. The first phase is scoped before work starts, so the first step is to define what needs to be built or improved, which backend/API/deployment decisions matter, and where architecture support should protect the implementation from avoidable rework.
It can be hands-on where the service scope calls for implementation, optimization, or delivery support. Architecture direction stays close to execution so the output does not become disconnected from what the team actually needs to build or fix.
The expected next step is production-grade web application, maintainable full-stack foundation, deployable system with monitoring. Some teams stop with the clarity they need; others continue into implementation, performance work, modernization, or ongoing technical leadership depending on what the engagement uncovers.
Yes. The same service can support a new build, MVP, production feature, backend/API improvement, mobile extension, dashboard, integration, or existing product upgrade. The scope is chosen around the highest-value development work first.
Yes. AWS deployment with Docker, CI/CD pipelines, environment management, and monitoring are part of the production-readiness work.
You receive hands-on software development support tied to the current product goal, not a generic consulting document. The work is shaped around frontend, backend, api, database, authentication, and admin workflow development, custom dashboards, portals, workflow tools, and saas interfaces, with enough architecture support to keep the build maintainable, deployable, and clear for a founder, CTO, or engineering team.
Yes. The engagement is designed to work with founders, CTOs, engineering leads, and existing product teams. The goal is to add senior development capacity, improve implementation quality, keep backend/API/deployment decisions clear, and use architecture judgment only where it improves the build.
The common stack coverage includes Next.js, React, Node.js, Express.js, TypeScript, PostgreSQL, and related infrastructure or product systems. The exact focus depends on where the service risk, delivery pressure, or product opportunity is showing up.
Yes. The service is shaped for US and UK founders, agencies, startups, and B2B SaaS teams that need remote development support with clear communication, senior technical ownership, and practical documentation.
The work starts with the smallest useful product scope, then adds enough backend, API, deployment, documentation, and architecture support to keep the product maintainable. The goal is not a bloated build; it is a product that can launch and improve without becoming fragile.
Best for US and UK high-growth B2B SaaS and AI businesses that need software architecture clarity, technical leadership support, and a better next step before complexity compounds business risk.
